Bug 167041 – Make tracking which Animation properties are set or filled more efficient

• Component: Animations
• Status: REOPENED

[Said Abou-Hallawa]

-- Shorten the enum names and use enum class instead.
-- Use std::optional for the members instead of tracking setting them variable by a set of booleans.

Is this correct?

No it is not correct. I do not remember how it happened. It looks like it happened because of either a bad merge or a bad copy/paste.

Why not initialize these in the class definition/

> +    , m_timingFunction(initialTimingFunction())
> +    , m_timingFunctionSet(false)

Could we instead use an optional or use RefPtr and have null mean not set? If keeping a separate boolean, could we initialize in the class definition?

> Source/WebKit2/Shared/CoordinatedGraphics/CoordinatedGraphicsArgumentCoders.cpp:530
> +        animationObject->setTimingFunction(*timingFunction.leakRef());

I don’t see how this could be correct. There’s a reason this function is named "leak". Are you sure tis is right?

This patch no longer applies (per EWS). I did not review whether it's a good idea, but r- for not applying any more.

[Said Abou-Hallawa]

This patch does not apply anymore. The code has changed a lot. So resolve it as INVALID.

[Antoine Quint]

Actually, using std::optional<> would be nice rather than keeping two sets of instance variables. Re-opening this and rephrasing.

[Antoine Quint]

Re-opening to fix.

[Antoine Quint]

Might be even better to use Markable here.

[Antoine Quint]

Actually, we should go beyond tracking which properties are set and also improve how we track which properties are filled.
